Exciton Dynamics in Layered Halide Perovskite Light‐Emitting Diodes

Advanced Materials, EarlyView.
This review discusses the exciton dynamics in layered halide perovskitelight‐emitting diodes (PeLEDs). It opens with a summary of the structural and photophysical aspects, followed by an exploration of controlling dimensionality and cascade exciton transfer in quasi‐2D PeLEDs.

Production of goats by somatic cell nuclear transfer

Nature Biotechnology, 1999
In this study, we demonstrate the production of transgenic goats by nuclear transfer of fetal somatic cells. Donor karyoplasts were obtained from a primary fetal somatic cell line derived from a 40-day transgenic female fetus produced by artificial insemination of a nontransgenic adult female with semen from a transgenic male.

Somatic Cell Nuclear Transfer

Advances in Animal Biotechnology, 2019
In biological system, the term “cloning” has different meanings. Animal cloning, the somatic cell nuclear transfer (SCNT) cloning, became a buzzword when Dolly, the first mammalian species was born from the nuclear transfer of fibroblasts taken from adult sheep.

A New, Dynamic Era for Somatic Cell Nuclear Transfer?

Trends in Biotechnology, 2016
Cloning animals by somatic cell nuclear transfer (SCNT) has remained an uncontrollable process for many years. High rates of embryonic losses, stillbirths, and postnatal mortality have been typical outcomes. These developmental problems arise from abnormal genomic reprogramming: the capacity of the oocyte to reset the differentiated memory of a somatic

Risk of pathogenic virus transmission by somatic cell nuclear transfer: implications for xenotransplantation

Biology of Reproduction, 2022
Using somatic cell nuclear transfer for the generation of cloned and transgenic animals bears the risk of transmission of viruses, either by the oocyte or by the introduced donor cell. There is evidence that the zona pellucida (ZP) surrounding the oocyte

Somatic Cell Nuclear Transfer in Pigs

2023
Somatic cell nuclear transfer (SCNT) has been successfully applied to clone animals of several species. Pigs are one of the main livestock species for food production and are also important for biomedical research due to their physiopathological similarities with humans.

Robotic Batch Somatic Cell Nuclear Transfer Based on Microfluidic Groove

IEEE Transactions on Automation Science and Engineering, 2020
Somatic cell nuclear transfer (SCNT), which is an important procedure in cloning, has been conducted manually for decades. The operating efficiency drops sharply in batch SCNT because of the long-time observation under microscopy and the time-wasting ...

Cloning by somatic cell nuclear transfer

BioEssays, 1998
The birth of the first cloned mammals, produced by the introduction of somatic cell nuclei into enucleated oocytes, was an impressive and surprising development. Although the ethical debate has been intense, the important scientific questions raised by this work have been inadequately discussed and are still unresolved.

Somatic Cell Nuclear Transfer in Rabbits

2023
Somatic cell nuclear transfer (SCNT) is a technology that enables differentiated somatic cells to acquire a totipotent state, thus making it of great value in developmental biology, biomedical research, and agricultural applications. Rabbit cloning associated with transgenesis has the potential to improve the applicability of this species for disease ...

Somatic cell nuclear transfer in zebrafish

Nature Methods, 2009
We developed a method for somatic cell nuclear transfer in zebrafish using laser-ablated metaphase II eggs as recipients, the micropyle for transfer of the nucleus and an egg activation protocol after nuclear reconstruction. We produced clones from cells of both embryonic and adult origins, although the latter did not give rise to live adult clones.
